Vision01:24

Vision

60.3K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Color Vision01:24

Color Vision

1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.2K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.6K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Social Cognitive Perspective on Personality01:30

Social Cognitive Perspective on Personality

1.0K
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Criticisms of the Evolutionary Perspective

In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

Area of Science:

  • Nanotechnology
  • Biomedical Engineering
  • Spectroscopy

Background:

  • Localized Surface Plasmon Resonance (LSPR) is a sensitive biodetection technique using plasmonic nanostructures.
  • Current LSPR sensors often require sophisticated spectrophotometers, limiting widespread adoption.
  • Cost-effective and simple detection methods are needed for broader LSPR sensor applications.

Purpose of the Study:

  • To develop a strategy for visualizing minute optical responses in nanoplasmonic bioassays using human color vision.
  • To identify an optimal wavelength range for naked-eye detection of LSPR shifts.
  • To enhance aggregation-based nanoplasmonic colorimetric assays for improved sensitivity and usability.

Main Methods:

  • Utilized nine different plasmonic nanoparticles to identify the cyan-to-green transition zone (~500 nm) for optimal color change detection.
  • Investigated wavelength shifts of ~2-3 nm induced by refractive index changes and molecular binding.
  • Applied the strategy to matrix metalloproteinase 7 (MMP7) activity detection using aggregation assays and cell phone-based RGB analysis.

Main Results:

  • Demonstrated that the ~500 nm wavelength range allows naked-eye detection of ~2-3 nm LSPR shifts.
  • Achieved a 5-fold increase in sensitivity for naked-eye detection of MMP7 activity compared to previous assays.
  • Validated the use of cell phone technology and RGB analysis for sensitive and quantitative MMP7 detection.

Conclusions:

  • The developed strategy enhances nanoplasmonic bioassays for naked-eye detection by exploiting human color perception.
  • This approach significantly improves the sensitivity and accessibility of LSPR-based biosensing, particularly for MMP7 detection.
  • The method holds great potential for medical diagnostics and environmental monitoring in resource-limited settings.
